java - Trying to create a DvbBufferedImage but its width and height are 0 -


i'm trying create fade-in animation using dvbbufferedimage bd-j application changing alpha value of images,

doublebuffer = new dvbbufferedimage(1920, 2180, dvbbufferedimage.type_advanced);

but after creates buffer, width , height 0 , when i'm trying graphics: 

dvbgraphics buffergraphics = doublebuffer.creategraphics();

it returns null.

after that, want draw images onto buffer , nullpointerexception. have , suggestion? think related libraries, because when replaced dvbbufferedimage bufferedimage using code: 

protected bufferedimage bufimage = new bufferedimage(1920, 2180, bufferedimage.type_int_argb );

it says :

the constructor bufferedimage(int, int, int) undefined

i mention i'm using customized eclipse developing bd-j applications , java version jre1.8.0_77.

classes used application listed below:

basis.jar btclasses.zip j2me_xml_cdc.jar javatv.jar jsse-cdc.jar pbp_1_0.jar sonicbdj.jar

your appreciated on problem, in advance!
